The LED indicators of the switch include Power, 100/1000Mbps, and Link/Act. The following shows the LED indicators for the switch along with an explanation of each indicator.

LED Indicators:

Comprehensive LED indicators display the conditions of the switch and status of the network. A description of these LED indicators follows (see LED Indicators). The LED indicators of the switch include Power, Link/Act, 1000Mbps, and 100Mbps.

Power Indicator

This green indicator illuminates when the switch is receiving power.

Link/Act

This green indicator illuminates steadily when a port is connected to a station successfully and has a good link. The indicator will blink to indicate that a port is transmitting or receiving data on the network.

Speed − 1000Mbps/Green; 100Mbps/Amber; 10Mbps/Off

This indicator is amber-colored when the port is connected to a 100MbpsFast Ethernet station. It is green when the port is connected to a 1000Mbps Ethernet station. It is not illuminated when the port is connected to a 10Mbps Ethernet station.

Auto MDI/MDI-X Ports:

Gigabit Ethernet Auto-Negotiating ports (10/100/1000Mbps) Comprehensive LED indicators display the conditions of the switch and status of the network.

AC Power Jack:

The power cable connection is located on the rear panel of the switch.

Switch power input is provided by and internal universal power supply (100-240VAC : 50-60Hz, 0.4A Max: 12V/3.3A).
The AC power connector is a standard three-pronged connector that supports the power cord. Please see the Power On section below for instructions on how to properly connect the switch to a power source.

In order for the Unified Switch to be able to discover and manage access points, the WLAN switch and its operational status must both be enabled. The WLAN component is enabled by default.

When you access the switch user interface, make sure you set the correct country code for the switch so that the access points can only operate in the modes permitted in your country. The default country code is US for operation in the United States.

NOTE:Wireless features are available under the WLAN tab on the navigation menu.

NOTE:Most configuration pages have a Submit button, which applies the changes to the running configuration but does not save them to non-volatile memory (NVRAM). To make the changes permanent so they persist across a reboot,click the Tool, then click Save Changes to navigate to the appropriate page.You can also use the write command in Privileged Exec mode.

Basic Wireless Global Configuration

1.Enable WLAN Switch

Check the box to enable WLAN switching functionality on the system. Clear the check box to administratively disable the WLAN switch.

If you clear the check box, all peer switches and APs that are associated with this switch are disassociated.

Disabling the WLAN switch does not affect non-WLAN features on the switch, such as VLAN or STP functionality.

2.WLAN Switch Operational Status

Shows the operational status of the switch. The status can be one of the following values:

• Enabled
• Enable-Pending
• Disabled
• Disable-Pending

If the status is pending, click Refresh to refresh the screen.

3.WLAN Switch Disable Reason

If the status is disabled, this field appears and one of the following reasons is listed:

• None—The cause for the disabled status is unknown.
• Administrator disabled—The Enable WLAN Switch check box has been cleared.
• No IP Address—The WLAN interface does not have an IP address.
• No SSL Files—The D-Link Unified Switch communicates with the APs it manages by using Secure Sockets Layer (SSL) connections. The first time you power on the Unified Switch, it automatically generates a server certificate that will be used to set up the SSL connections. The SSL certificate and key generation can take up to an hour to complete.

If routing is enabled on the switch, the operational status might be disabled due to one of the following reasons:

• No Loopback Interface—The switch does not have a loopback interface.
• Global Routing Disabled—Even if the routing mode is enabled on the WLAN switch interface, it must also be enabled globally for the operational status to be enabled.

IP Address

This field shows the IP address of the WLAN interface on the switch. If routing is disabled, the IP address is the network interface. If routing is enabled, this is the IP address of the routing or loopback interface you configure for the Unified Switch features.

AP Authentication

Select the check box to require APs to be authenticated before they can associate with the switch.

AP MAC Validation

Select the database to use for AP validation.

• Local—If you select this option, you must add the MAC address of each AP to the local Valid AP database.
• RADIUS—If you select this option, you must configure the MAC address of each AP in an external RADIUS server.

Country Code

Select the country code for the country where your switch and APs operate.A popup window asks you to confirm the change.

Wireless regulations vary from country to country. Make sure you select the correct country code so that your WLAN system complies with the regulations in your country. Some WLAN modes, such as the Atheros modes, are not available in some countries.

Changing the country code disables and re-enables the switch. Any channel and radio mode settings that are invalid for the regulatory domain are reset to the default values.

The country code (IEEE 802.11d) is transmitted in beacons and probe responses from the access points.

From the CLI, you can view the same information that is available on the Wireless Global Configuration page with the show wireless command in Privileged EXEC mode. If you need to change the country code, you can view the list of available countries and their twoletter codes with the show wireless country-code command.

The CLI commands to set the country code and enable the WLAN switch are available in Wireless Config mode. To set the country code, enter country-code . To enable the WLAN switch, enter enable. The following example shows how to access Wireless Config mode, set the country code to Canada, and enable the WLAN switch.

After you perform the physical hardware installation, you need to connect the D-Link Unified Switch to the network. The default IP address of the switch is 10.90.90.90/8, and DHCP is disabled by default. If you want to enable DHCP on the switch or assign a different static IP address, you must connect to the switch and change the default settings.

You can connect to the switch through Telnet or a Web browser from a host on the 10.0.0.0/8 network, or you can connect to the switch through the console port (RS-232 DCE). After you connect to the switch, you can provide network information or enable the DHCP client.

To connect to the D-Link switch from a host on the 10.0.0.0 network, enter the default IP address of the switch (10.90.90.90) into the address field of a Web browser or a Telnet client.

To connect to the console port and provide network information, use the following steps:

1. Using a null-modem cable, connect a VT100/ANSI terminal or a workstation to the console (serial) port.

If you attached a PC, Apple, or UNIX workstation, start a terminal-emulation program,such as HyperTerminal or TeraTerm.

2. Configure the terminal-emulation program to use the following settings:

Enter admin as the user name. There is no default password. Press ENTER at the password prompt if you did not change the default password.

After a successful login, the screen shows the (switch-prompt)> prompt.

4. At the (switch-prompt)> prompt, enter enable to enter the Privileged EXEC command mode. There is no default password to enter Privileged EXEC mode. Press ENTER at the password prompt if you did not change the default password.

Connecting the Switch to the Network

You can use any of the 1000BASE-T ports, 10GB ports, or fiber-optic ports to connect the D-Link Switch to your network. The type of port you use to connect the switch depends on your network requirements and the type of node to which you connect the Switch, which might be a hub, router, or another switch.

There is a great deal of flexibility on how connections are made using the appropriate cabling.

• Connect a 10BASE-T hub or switch to the Switch via a twisted-pair Category 3, 4 or 5 UTP/STP cable.
